   odd.  It definitely worked for me when I was testing the change.   
      
   The change in #407 was for a case where the box was drawn and then   
   immediately overwritten because the width was seen as zero because   
   wcwidth could return zero either because of a valid combining   
   character or because it was missing from the Unicode database.   
      
   The initial report stated   
      
   	This U+0FE0 does not exist in the Unicode database here, but in any   
   	case, it should be handled in a consistent way.   
      
   so I'll keep that goal.
